TRESPASSERS by Raymond Duncan

Mexicans are crossing the U.S. border illegally in alarming numbers and terrorist acts are taking place at the boundary line. Protest marches in Phoenix over a “Stolen Southwest” only aggravate an explosive situation due to violent white supremacist militias' backlash. The CIA, tasked to investigate this escalating national security threat, recruits Professor Neal McGrath to help. McGrath, a former Special Forces officer who has worked previously with Langley, has valuable contacts in Mexico City. To add to the tension, the beautiful CIA operative, Elena Rodríguez, with whom McGrath shares a romantic and dangerous past, is assigned to work with him. Together they unearth a deadly international conspiracy that puts their lives in danger at every turn.
